A mother and her young son were flying Southwest Airlines from Kansas City to Chicago. The son turned from the window to his mother and asked, "If big dogs have baby dogs and big cats have baby cats, why don't big planes have baby planes?"
The mother said, "Well, maybe that's something you could ask the stewardess."
So the boy asked the stewardess, "If big dogs have baby dogs and big cats have baby cats, why don't big planes have baby planes?"
The stewardess responded, "Did your mother tell you to ask me?"
The boy admitted that this was the case. "Well, then, tell your mother that there are no baby planes because Southwest always pulls out on time. You can ask your mother to explain it to you."
The mother said, "Well, maybe that's something you could ask the stewardess."
